.SH NAME
std::ratio_greater_equal \- std::ratio_greater_equal

.SH Synopsis
   Defined in header <ratio>
   template< class R1, class R2 >
   struct ratio_greater_equal : std::integral_constant<bool, /* see       \fI(since C++11)\fP
   below */> { };

   If the ratio R1 is greater than or equal to the ratio R2, provides the member
   constant value equal true. Otherwise, value is false.

.SH Member constants

   value    true if R1::num * R2::den >= R2::num * R1::den, or equivalent expression
   \fB[static]\fP that avoids overflow, false otherwise
            \fI(public static member constant)\fP

.SH Member functions

   operator bool converts the object to bool, returns value
                 \fI(public member function)\fP
   operator()    returns value
   \fI(C++14)\fP       \fI(public member function)\fP

.SH Example


// Run this code

 #include <iostream>
 #include <ratio>

 int main()
 {
     static_assert(std::ratio_greater_equal<
         std::ratio<2, 3>,
         std::ratio<2, 3>>::value, "2/3 >= 2/3");

     if (std::ratio_greater_equal<
         std::ratio<2,1>, std::ratio<1, 2>>::value)
         std::cout << "2/1 >= 1/2" "\\n";

     if (std::ratio_greater_equal<
         std::ratio<1,2>, std::ratio<1, 2>>::value)
         std::cout << "1/2 >= 1/2" "\\n";

     // Since C++17
     static_assert(std::ratio_greater_equal_v<
         std::ratio<999'999, 1'000'000>,
         std::ratio<999'998, 999'999>> );

     if constexpr (std::ratio_greater_equal_v<
         std::ratio<999'999, 1'000'000>,
         std::ratio<999'998, 999'999>>)
         std::cout << "999'999/1'000'000 >= 999'998/999'999" "\\n";

     if constexpr (std::ratio_greater_equal_v<
         std::ratio<999'999, 1'000'000>,
         std::ratio<999'999, 1'000'000>>)
         std::cout << "999'999/1'000'000 >= 999'999/1'000'000" "\\n";
 }

.SH Output:

 2/1 >= 1/2
 1/2 >= 1/2
 999'999/1'000'000 >= 999'998/999'999
 999'999/1'000'000 >= 999'999/1'000'000
